feat(arch): the plan model and its foundation - layers, materials, EN/TR, two generalisations
Track F starts here; the three group branches are cut from this commit. - engineering/arch/model.py: Wall, Opening, Stair and Room as frozen dataclasses, and every refusal of spec 4 before anything is drawn, by path (walls[2].thickness): finite positive numbers, an axis of at least two distinct points with no zero-length segment, an arc segment refused by name rather than approximated, an opening on an unknown wall, past its wall, across an axis vertex or overlapping another (both ids named), an unknown material, and a typed room area - areas are measured, never typed. The plan travels as ACADMCP_ARCH XDATA; an opening's door/window kind and a stair's straight/l/u kind ride beside the payload kind as opening_kind / stair_kind, because one key cannot hold both. - engineering/arch/layers.py: the arch set - thirteen ISO 13567-style layers with ISO 128 lineweights only (0.05 mm on the construction scratch layer, as every set in this repository) - and ARCH_ROLE_LAYER, the one place a role becomes a layer. Registered in engineering/layers.py last, which is what keeps the engineering.layers <-> engineering.arch import cycle closed. - engineering/arch/materials.py: eight wall materials, one pattern each, every row citing its source: ANSI31 for brick (ISO 128-50 general hatching, acadiso.pat's own "Iron, Brick, Stone masonry"), AAC as ANSI31 at twice the spacing (a repository convention, and it says so), AR-CONC / AR-SAND as AutoCAD patterns, and the JIS A 0150 RC / stone / wood symbols. Reinforced concrete cannot be ANSI31 and AR-CONC in one HATCH, so it takes the one symbol that names it. Periods on a 1:50 sheet are recomputed from ezdxf's own pattern definitions by the tests. normalise_material is the one reading of a material name, shared by the model and wall_hatch, so the model never refuses "Reinforced Concrete" that the hatch table resolves. - engineering/arch/lang.py: EN / TR vocabulary, D/W and K/P tag prefixes, and the decimal comma for lang="tr" (24,50 m2). - draw_prims(role_layer=) and the XDATA codec's app_id= / kinds=: both generalised with the mechanical defaults, and the mechanical suite passes unchanged against them - that is the regression gate.

fix(com): hatch islands on a live seat — typed edges become temporary entities
hatch_add_boundary was refused on COM (hatch_edge_paths), so a transverse section of any hollow part — a bushing, a flange bore — could not be drawn in AutoCAD at all: draw_prims asked the capability map and refused up front. ActiveX takes a loop as whole objects, which is not the same as "cannot take a typed edge": each edge now becomes a real temporary LINE, true ARC or ELLIPSE in the hatch's own space, appended with AppendInnerLoop, evaluated and deleted. A loop that is only chained lines becomes one closed polyline — one COM call instead of 180 for a flattened bore. The edge list is validated in full first with the headless engine's messages; a loop AutoCAD refuses is taken back out with its temporaries. Measured on AutoCAD 2026 (25.1s), in scratch documents closed unsaved: - a two-arc island leaves exactly 10000 - 100*pi (9685.8407) of a 100 x 100 hatch; - the OD40/ID20 sleeve's transverse section B-B, drawn through the view engine and draw_prims, hatches 942.2864 mm2 — the engine's declared 180-gon; - an open chain is refused (E_FAIL) and the entity count is unchanged. hatch_edge_paths is now supported on both engines.

bench: matrix v5 adds mech_assembly; the correctness suite grows with the mechanical and sheet checks
The evidence for tracks B and G, in the shape tracks A and E used.
- benchmarks/tasks_v5.py: 18 tasks, DEFAULT_MATRIX = "v5"; v4, v3 and v2 stay
addressable so an earlier report reproduces exactly rather than being only
described. mech_assembly is roadmap criterion 3 - a flange-coupling sheet
built from the part model and the sheet standard, through the code the
tools call (apply_titleblock, draw_part/add_view/dimension_part,
insert_std_part, extract_records -> draw_bom_table, add_balloon), gated on
two numbers that cannot be negotiated: drawing_critique(focus=None) returns
zero issues and the finalize score is at least 90 (it scores 100, 18/18 on
the v5 matrix). The adapter returns the focuses that fired, so a
regression names itself, and a test drops one balloon to prove the gate
fails and names mech_bom_balloon_mismatch.
- Seven correctness checks (32 -> 39). mech_section_hatch_area is the one
that cannot be faked: a sleeve of length 60, outside diameter 40 and bore
20 cuts two faces totalling 1200 mm^2 exactly, read back out of the drawing
through entity_measure. sheet_frame_iso5457_a3 pins the A3 frame (20,10 to
410,287 inside the 420 x 297 trimmed sheet); mech_iso286_on_dimension pins
40 H7 at +0.025/0 through the layout; std_part_iso4014_m12 pins s = 18 and
k = 7.5 by value; mech_thread_unrepresented_is_caught is the seventh: a
quality gate that never fires is not a gate.
- scripts/smoke_mech_com.py executed every new COM path once on AutoCAD 2026
(25.1s): frame, title block, a sectioned shaft with 12 dimensions, an ISO
4014 block with 1 ACADMCP_MECH chunk, a weld symbol, the parts list read off
the drawing, a linked balloon, an xref attached / listed / detached, a
31687-byte .dwg (AC1032) through ActiveX SaveAs, critique 0 issues, exit 0,
every scratch document closed. It retries RPC_E_CALL_REJECTED (measured:
the first call after Documents.Add is refused) and tracks its documents by
the document list, since SaveAs renames them.
- Defects the evidence found, each fixed with a test that fails on the old
code:
* ezdxf dimension_diameter put the text beyond the SECOND chord point;
ActiveX AddDimDiametric puts it beyond the first (measured live: a d50
from (x,170) to (x,220), leader 10, text at (x,160)). Headlessly every
front-view diameter stood on its own chain dimension. ezdxf now follows
ActiveX.
* draw_part's anchor goes on MECH; ActiveX refuses entity.Layer on a
missing layer (measured -0x7ffdfff7 'Key not found'). draw.py ensures
every target layer before the first entity.
* bom.extract_records filtered on INSERT; ActiveX names it BLOCKREFERENCE
(ObjectName AcDbBlockReference) - the live parts list was empty.
* COM _entity_info reported no dimension text_position: ModelSpace.Item
narrows to IAcadEntity, which has no TextPosition (measured
AttributeError); read through _com_unnarrow (TextPosition measured on
AcDbDiametricDimension, WCS). dim_overlap compared bbox centres and a
diameter collided with its own bore.
* pid graph raised KeyError 'start' mid-critique on a LINE whose point read
AutoCAD refused while busy; such a line is left out.
* the validator read "ISO 4014 - M12x60" as fake dimension text.
- The published A/B report is re-run over the grown suite rather than
re-typed (26/39 -> 39/39, 13 fixed, 0 regressed), check_doc_numbers derives
the task count from the v5 matrix, the token table is remeasured with a
TOOL_PACKS=core,mech row (193 tools / 61,673 tokens), and the README's
collected-tests figure is retaken (3990).

feat(mech): six mech_* critique focuses, the mech pack, lean 60, aliases and the counts
The four track-B/G branches are merged; this is the integration that makes the 25 new tools one surface instead of four. - engineering/mech/critique.py: the six focuses of spec 13, dispatched the way the P&ID ones are. One index per critique run, shared through run_critique's context, so six focuses cost one read of the drawing; a drawing with no ACADMCP_MECH payload yields nothing at all, which is what keeps focus=None cheap for a P&ID sheet or a plain DXF. Each focus has a positive and a negative fixture. Two narrowings are in the module docstring rather than hidden: mech_view_misaligned checks the projection axis and not the quadrant, because the pinned payload carries no projection angle to check it against, and mech_duplicate_dimension catches two dimensions in the same place rather than a semantic restatement, because no engine exposes what a dimension measured. - The index reads what the tools actually write, not only the plan's fixture shape. mech_part_draw anchors its part payload on a POINT (layer MECH) and lists every drawn view under "views"; the plan's index read INSERT/CIRCLE only and one "view" per payload, so it was silent on every part the server draws. It now reads POINT too, expands "views" into one entry per drawn view (the section check looks in the section's own WCS box, the alignment check compares frame_bbox centres), and pages entity_list instead of one call. Test: a part drawn by draw_part + add_view is read and passes all six; the same part with its hatch erased is reported. - Live type names, measured on AutoCAD 2026 (2026-09-23, scratch document, closed): ObjectName AcDbBlockReference -> BLOCKREFERENCE, AcDbRotatedDimension -> ROTATEDDIMENSION, AcDbAlignedDimension -> ALIGNEDDIMENSION, AcDbPoint -> POINT with GetBoundingBox = the point. The index reads BLOCKREFERENCE as an INSERT and any *DIMENSION as a dimension; a wrapper test reports the ezdxf entities under exactly those measured names. - mech_thread_unrepresented uses the view engine's own MINOR_RATIO, and checks the thin line ISO 6410 draws: the minor diameter of an external thread, the major of an internal one. - mech_bom_balloon_mismatch: identical parts share one balloon (ISO 6433 balloons a parts-list row), so a second M12x60 is covered by the first one's balloon instead of reported. - TOOL_PACK_NAMES has "mech" (the 14 tools of SECTIONS 21-23). SECTION 24 stays core: a frame, a title block, a parts list and an xref are universal drafting, not a vertical. Lean gains five and reaches 60 (54 with TOOL_PACKS=core). - _GROUP_TAG_PRIORITY gains sheet directly after mech; the mech group label becomes "mechanical". SECTION 24's last four tools (xref_attach, xref_manage, image_attach, drawing_export_dwg) now carry the sheet tag, so group, pack and SECTION are one list: 229 tools in 25 groups, and engineering/blocks/entity_creation/drawing return to their pre-SECTION-24 sizes. - Ten golden tuning cases, two of them Turkish (with the diacritic spellings added to the alias records next to the ASCII-folded ones). The shared AutoCAD command set needed no change: the merge had already resolved TABLE, REVCLOUD, SECTIONPLANE, INSERT, ARRAY and SAVEAS, and nothing is stale. - Inventory regenerated, the frozen group-size snapshot retaken from the live registry, and the README release-snapshot / pack / lean figures taken from scripts/check_doc_numbers.py rather than typed.

fix(task-7): rotation honoured end to end, each view dimensioned once, refusals that name their path
- rotation turns the whole sheet of views about `at` as one rigid body: the
prims, the recorded WCS `bbox` (plus the sheet-frame `frame_bbox` the next
view is laid out against), the detail marker, and every dimension intent
(points, text position, and the linear measuring direction + rotation).
Measured headless: rotation=90 at (100,100) now draws (70,100)-(100,172),
records exactly that box, and leaves only the 2 diameter chord defpoints
off-geometry (was 4, up to 47.5 mm away).
- dimension_part dimensions only views whose record is not `dimensioned`,
takes `views=[indices]`, refuses a view already dimensioned by name
(ISO 129-1), writes the flag back, places the hole table once, and refuses
a fit no target view claims before drawing anything. A view the dimension
layer emits nothing for (a detail) is reported in `skipped` and left
unflagged. mech_dimension_part gains the `views` argument.
- draw_prims checks hatch_add_boundary's {"ok": False}: the hatch is removed
and the failure raised, never left solid through the bore. An engine whose
capability map says `hatch_edge_paths` is unsupported (the live one) is
refused before any prim of the view is drawn.
- a view scale other than 1.0 is refused by name in draw_part and add_view
(views are drawn full size; the scale would only have been recorded).
- add_view's collision step compares real rectangles on both axes and steps
along the projection axis layout_origin chose, so a third-angle view is
never shoved back onto the front view and a top view keeps its alignment.
- draw_from_spec validates `at` / `rotation` into the `parts[i]:` path and a
transaction that cannot open is a ValueError (a ToolError at the tool).
No new ActiveX member is called: the change composes existing contract
members (dimension_linear rotation, entity_delete, capabilities()).

feat(task-7): SECTION 21 - the mechanical part model as six tools
engineering/mech/draw.py is the only module in the package that touches a backend: it turns the pure engine's primitive descriptions into entity_create_* and dimension_* calls, places them in WCS, and writes the part model back onto the drawing as ACADMCP_MECH XDATA on an anchor POINT. It is not a contract member and neither are the tools - exactly like gear_draw_* and titleblock_apply_iso_a3, it composes the generic members, so it is written once and works on both engines by construction and no capability key is needed. No new ActiveX call was written, so there was nothing to probe on the live seat; measured instead that every one of the 23 backend members draw.py calls exists on ComBackend and that ComBackend has no abstract methods left. mech_part_draw takes one model - a turned profile or a plate outline plus typed features - and draws its views in first-angle positions (third on request), dimensions them and records the placement. mech_view_add reads the model back out of the drawing and adds a side, top, section (full/half/offset/revolved) or detail view months later without the caller re-describing the part. mech_dimension_part lays out ISO 129 dimensions with no overlapping text, resolves ISO 286 fits against the measured nominal, and moves the holes into a table past a threshold. mech_hole_pattern exposes the same expansion for a drawing that was never built from the model - with its own diameter guard, because Hole.validate needs a part and a standalone pattern has none. mech_part_inspect reads the payload back and never modifies the drawing. mech_part_from_spec draws a whole sheet inside one transaction. Every part is validated before the transaction opens, so a refusal leaves the drawing untouched and names the path (parts[1]: segments[0].d_outer: ...), and the rollback is shielded with the shape engineering/pid/spec.py documents: anyio cancellation is level-triggered, so a bare await in the handler would be cancelled before the rollback body ran and leave half a sheet inside an open transaction. fits goes through dimension_intents(fits=...), the API Task 6 shipped, rather than being stamped on at draw time: that is the path that validates a key by name and refuses a fit on a reference dimension or on a hole that moved into the table. It is scoped per view first - a fit on segment[0] names nothing in the end view, and refusing there would make a correct three-view sheet undrawable - and any key no view claimed is handed back to dimension_intents so the refusal is written in its own vocabulary. SECTION 21 registers the six tools in the new mech pack, with alias records (SECTIONPLANE, ARRAY plus shop-floor synonyms in English and Turkish - mil, kademeli mil, kama, pah, kesit, gorunus), a regenerated tool inventory, the README release snapshot at 210 tools in 24 groups, and the frozen group-size snapshot gaining mech: 6. Lean is deliberately untouched here: spec section 11 puts three of these on the lean surface together with group G's two sheet tools, and Task 15 makes that edit once across all four branches.

fix(task-6): a reachable ISO 286 route, a tolerance schema that refuses, a reference dimension
Three review findings, all root causes in `engineering/mech/dimension.py`.
1. The ISO 286 fit path was unreachable from the module's own pipeline.
`resolve_tolerance` resolved `intent.fit` correctly, but nothing produced a
DimIntent carrying one: no feature and no segment has a fit, and
`dimension_intents` constructed every intent without `fit=`. Only a
hand-built DimIntent - which is what the tests used - reached the code, so
the spec's `mech_iso286_on_dimension` and the `mech_assembly` benchmark's
"ISO 286 fits on the bearing seats" had no route.
`dimension_intents(..., fits={key: code})` now stamps the code onto the
intent its key names, and the part's own diameters became addressable one
at a time through the new `segment_key(i, bore=...)` -> "segment[1]",
"segment[1].bore"; a feature's stay addressable by id. A key that names
nothing is refused with the names that exist, a malformed code is refused
where it is attached rather than at draw time, a fit on a reference
dimension or on one that already carries a tol is refused, and a fit on a
hole whose diameter moved into the hole table (which has no tolerance
column) is refused by name instead of vanishing. Task 7's planned
`dimension_part(..., fits=None)` passes straight through - the argument is
additive and keyword-only, so every call written against the pinned
signature keeps working.
The fit also now reaches the *text*: `intent_text` expands the `<>`
placeholder and appends the code, so `text_rects` measures the string that
is actually drawn and a hole that already names itself ("⌀6") keeps its own
text and gains the code.
2. An explicit tolerance was silently discarded when `tol` omitted "mode".
`mode = tol.get("mode", "none")` and `build_dim_override(0.05, 0.05,
"none", None)` returns `({}, None)` without raising, so a ±0.05 resolved,
echoed its own numbers back in the payload, and drew a dimension with no
DIMTOL/DIMTP/DIMTM at all. `DimIntent.tol` now has a schema - {"mode",
"upper", "lower"} and nothing else - validated by `_explicit_tol`: an
unknown key, a missing "mode", a non-dict, and deviations under a mode that
writes none are each refused by name. The mutual-exclusion guard reads
`tol is not None` rather than truthiness, so `tol={}` is refused too.
3. The ISO 129-1 "no measurement twice" test was vacuous and the property was
false. The old test built the key `_dedupe` uniquifies as the last step of
`dimension_intents`, so it could not fail; meanwhile `style="chain"` emitted
20, 40, 15 *and* 75 as four plain DIMENSIONs. `redundant_linear` now finds
the span that shorter ones tile end to end on the same axis and level, and
`dimension_intents` marks it as an auxiliary (reference) dimension - the new
`REFERENCE_FORMAT` "(<>)", which renders "(75)". The plan's own test still
holds (the 75 is present); it is no longer a fourth plain dimension. The
error is one-sided on purpose: a tiling that is found is real, a tiling the
greedy walk misses leaves the dimension plain, which is the direction the
repository's critique rule wants. Baseline and ordinate parenthesise
nothing, and two horizontal chains at different heights are not each other's
pieces.
Tests: the vacuous gate is replaced by four that fail against the pre-fix code
- `redundant_linear` on the shaft's plain intents returns (3,) there and ()
here; the parametrised "a tolerance is either refused or reaches the dimension
variables" gate resolves the mode-less shape to an empty DIMVAR override
there; and `fits=` is a TypeError there. `_dedupe` is now exercised through a
duplicate fed in via the view's own dims, which the collector does not
generate itself. 46 tests in tests/test_mech_dimension.py (was 23).
Live AutoCAD: no finding was measured live and no new ActiveX call was
written - this module is pure Python with no backend, no async and no DXF. A
DIMTOL probe against the running seat was attempted twice and
`GetActiveObject("AutoCAD.Application")` blocked past the ~90 s contention
window both times, so the live engine was unavailable; no scratch document was
created (the probe never got the application object) and none was left open.

feat(task-6): dimension intents, ISO 286 fits and an overlap-free layout
engineering/mech/dimension.py collects what the features asked to have dimensioned, adds the part's own sizes (chain, baseline or ordinate for the axial lengths, a diameter per segment and per bore, the two overall sizes of a plate), and removes the duplicates - ISO 129-1 says each dimension appears once, and a test asserts no measurement is placed twice. Fits and tolerances are resolved through the modules that already own them: engineering.fits for an ISO 286 code and engineering.tolerances for an explicit ISO 129 tolerance, including build_dim_override's sign convention (the lower deviation is passed as the magnitude of the minus side, exactly as server.py::_fit_to_tolerances does). A H7 bore at 40 mm resolves to +0.025/0 - the correctness check the spec names. A fit together with an explicit tolerance, a fit outside the authored ISO 286 range, and a fit on an intent with no measurable nominal are each refused by name rather than guessed. The layout is the part that had to be measured rather than asserted: every intent's text is turned into a rectangle by the same helper the test uses, and an intent is placed on the lowest level whose rectangle is free, with the level pitch clamped to clear the text whatever the caller passed. The test then asserts the placed rectangles are pairwise disjoint - including on a crowded plate and with a deliberately too-small step. That is the same property the repository's dim_overlap critique focus checks on the finished drawing. The plan's layout clamped that pitch to the text HEIGHT on every axis, which is only the stacking direction for the row of dimensions under the view. Beside the view the levels march in x, so the extent they have to clear is the text WIDTH: measured here, three diameter labels are 9.45 mm wide (9.45, 5.6) at a 8.0 mm pitch, so a shaft's three segment diameters - all on the y = 0 centreline, hence all on different levels - overlapped by 1.45 mm. The pitch and the within-level span are now both taken per axis from the same _text_size helper text_rects uses, which makes the disjointness a property of the algorithm rather than of the label lengths that happened to be in the test. Over hole_table_threshold holes the per-hole diameters leave the view and become a table instead, grouped by diameter, thread, counterbore and depth, one tag per group and the quantity on every row.

fix(task-5): cut faces on the real chord, cross sections that see features, a section with no dashed cut edge
Three defects, all of them the same mistake in three places: the cut face was built from something other than the geometry it claims to show. 1. A prismatic cut face removed a feature by its BOUNDING BOX. `Hole.removal_box` is a square, so the gap punched in the cut face was the full diameter wherever the plane passed. On the plan's 80x50x8 plate with a Ho10 hole at (40, 25): a plane at y=29.9 grazes the hole (true chord 1.990) and the section still showed an 8 mm gap through solid metal - 560.0 mm2 hatched against a true 624.08, a 64 mm2 error in the hatched area AND a wrong drawn outline. `Slot` had the same obround-as-box. Features now answer `cut_spans(part, p1, unit)` with their own exact chord: `_circle_chord` for a hole, the union of two circles and a rotated rectangle for a slot, the polygon's own crossings for a pocket, and an exact slab clip of `removal_box` as the default. `_box_span` (the corner projection, which is the box's shadow and not a chord at all) is gone. 2. A transverse revolved section ignored every feature and the honesty rule never fired. A cross section through a DIN 6885-1 keyway came out as a plain hatched disc with `omitted == ()` - the commonest mechanical cross section there is, hatched straight over the 12x5 keyway. The face is now built by `_transverse_face`: its radii come from `radial_profile` (so a groove, an undercut, a bore or an ISO 6410 internal thread is in the face already, which the raw segment diameters could not report), a non-axisymmetric feature is asked for its own `cross_section` notch record, and one the plane really passes through with no such record is listed in `omitted` with its reason rather than hatched over. `Keyway._notch` is the one calculation the end view and the cut face both come out of. 3. A section drew its own cut boundary as a HIDDEN (dashed) line, because the longitudinal branch reused `silhouette_prims` and the silhouette draws the bore dashed - correct for an un-cut view, wrong for a section, where that line IS the hatch loop's boundary. ISO 128-50 bounds a surface lying in the cutting plane with a continuous wide line and ISO 128-3 leaves hidden detail out of a sectional view; via ROLE_LAYER['hidden'] this would also have put the cut boundary on the HIDDEN layer in Task 7. New `section_profile_prims` emits the cut outline all-continuous, and `half=True` keeps the dashed bore on the -Y half only, which is the half a half section does not cut. And the claim the last commit made without earning it: the hatched area and the drawn outline are now literally one calculation. The longitudinal loop is the *emitted* outline flattened (`_flatten_path`), so a chamfer or fillet that substitutes a silhouette corner is cut out of the hatch exactly where it is drawn - a 2 mm 45 deg chamfer takes its 2 mm2 off the 1000 mm2 half face instead of being hatched over. Eleven new tests, every one of them red on the parent commit: the hole chord at 0/4/4.9 mm off centre, a tangent plane leaving the face whole, the 45 deg slot, the keyway cross section against its own analytic area, the feature a cross section cannot project, the feature the plane misses, the groove read off the profile, the continuous cut boundary, the half section's dashed half, and the chamfered cut face. No new ActiveX member is called: all three fixes are pure geometry in the backend-free `engineering/mech` package.

feat(task-5): sections, cut faces, material hatch and detail views
engineering/mech/views.py grows the two remaining view kinds. A section's cut
faces come out of the same radial profile the silhouette does, so the hatched
area and the drawn outline are one calculation and cannot disagree: a solid
shaft's half-section loop measures exactly the sum of its segment rectangles,
and a bore closes the loop on itself rather than being hatched over.
ISO 6410's section convention falls out of the model rather than being special-
cased: an internal thread's radial_edit already raises the bore to the major
diameter, so the hatch stops there. ISO 128-3's rib rule is a flag on the
feature - a pocket marked no_section_hatch is drawn and left unhatched, while
the rest of the cut face is hatched with the part's ISO 128-50 material.
Four styles, each either implemented or refused by name with the alternative
rather than approximated: full and half on a longitudinal plane through a
revolved axis; full and revolved on a transverse plane (the annulus, flattened
at 2 degrees - 0.015% of the radius, stated in CIRCLE_SEGMENTS rather than
hidden); full and offset on a prismatic part, where through features split the
cut face and pockets reduce it to the remaining thickness. A plane that misses
the part, or that grazes an outline vertex so its crossings cannot be paired, is
refused instead of producing a guessed cut face.
Details scale a circular region of a parent view, emit the ISO 128-34 circle and
letter for the parent and the "A (5:1)" label for the detail itself, and report
every feature that falls outside the circle in omitted - the honesty rule again.
Three test assertions were corrected to the measured truth rather than the
engine bent to them, each verified by running the code:
* the ISO 6410 test asked for the whole cut-face loop's minimum to be the M20
major (r=10). It is not, and must not be: over the 5 mm that is drilled but
not threaded the loop closes on the real 16 mm drill (r=8). The loop is
((0,10),(0,25),(25,25),(30,25),(30,8),(30,8),(25,8),(25,10),(0,10)). The test
now pins both spans, which is the convention it meant to assert.
* the transverse-annulus areas were pinned at rel=2e-4. An inscribed regular
180-gon is exactly 1 - (n/2pi) sin(2pi/n) = 2.0307e-4 under the circle, so
2e-4 rejects the very flattening CIRCLE_SEGMENTS declares. The tolerance is
now 2.1e-4 and the test computes the deficit and pins it, so the number is
derived rather than guessed. CIRCLE_SEGMENTS' docstring now states both
figures: 0.015% radial (the 2 degree chord's sagitta) and 0.0203% of area.
* tests/test_mech_views.py pinned VIEW_KINDS == ("front","side","top"), which
this task deliberately grows. It now pins the three orthographic kinds as the
first three and the full five-kind tuple.
_is_longitudinal takes only the plane; the plan's signature also took the part
and never read it.

fix(task-4): the end-view occlusion rule, the double-drawn groove, the left view
Three defects in the orthographic view engine, all one missing idea: the engine
had no visibility rule and no single owner for the silhouette.
1. `_end_circles` inverted the hidden-line rule. Walking the bands from the
viewing end it drew a circle only when its radius EXCEEDED everything nearer,
and roled every such circle `hidden` unless it was the first band - so the one
edge that CANNOT be occluded (a step face larger than the material in front of
it) shipped dashed on HIDDEN, and the circle that really is covered was not
drawn at all. `_front_max` is now the rule: an edge of radius r at station x is
continuous when r is larger than every outer radius between x and the observer,
dashed when it is not, and it is always drawn. Bores follow the mirror image -
you see down a bore only while it stays at least as wide. Each distinct radius
is emitted once, because two coincident circles are a duplicate entity.
The same rule now roles a feature's axis-centred end-view circle, whose axial
station comes from `removal_box`; a feature that reports none keeps its own
verdict rather than having one guessed.
Ground truth by ray cast along the axis of the same solid of revolution
(segments 20x25, 40x30, 15x20; observer at +X, probe just inside each edge):
r=10 at x=75 -> first surface x=75 -> VISIBLE (was visible, kept)
r=15 at x=60 -> first surface x=60 -> VISIBLE (was HIDDEN, fixed)
r=12.5 at x=20 -> first surface x=60 -> HIDDEN (was not drawn, fixed)
2. Every axisymmetric groove was drawn twice - once as the notch
`radial_profile` cuts into the silhouette, once by the feature's own
`prims()`, which `_feature_layer` appended unconditionally. Six exactly
coincident LINEs per grooved shaft, which is precisely what
`critique.py::_check_duplicate_entities` matches, so premium rule 7 could
never be met on a part carrying a retaining or O-ring groove. `_profile_owned`
now drops a feature primitive that the body already emitted, and drops a
revolved front view's `visible` silhouette line from any feature that edits
the radial profile: the spec's rule is that grooves cut a notch in the
silhouette, and the notch belongs to the one calculation. Suppression is
"the profile already drew this", not "this feature edits the profile", so a
blind bore keeps the bottom line the profile cannot express, and an internal
thread keeps its ISO 6410 limit line.
A groove straddling a step was worse than duplicated: the feature reads one
surface radius for a span that has two, so it drew a groove floor through
solid material and left the +Y path with four odd-degree nodes. It now has
two - its two ends on the axis.
3. `build_view` validated `side` and put it in ctx, but the prismatic branch
ignored it: `side="left"` returned the right-hand view, with every feature on
the wrong side of the sheet and a symmetric outline rectangle to hide it. An
observer at -X sees screen-right = -Y, so the feature layer is now mirrored
about the outline's mid-Y. The top view is always seen from above and does
not move with `side`; that is now said in the docstring and pinned by a test.
Tests: the two that pinned the inverted rule are rewritten around the ray cast,
and one of them contradicted its own name. Seven tests added, and the prismatic
side-view test's hole moved off the y=25 mirror axis, where it could not tell a
left view from a right one. Nine of them fail against the previous `views.py`
and pass against this one.
Live AutoCAD was unavailable for a SOLPROF cross-check: the running AutoCAD 2026
(pid 40068) reports Responding=False and `GetActiveObject("AutoCAD.Application")`
never returned inside 100 s, so no scratch document was created and none is left
open. No new ActiveX member is called by this change - views.py is pure.

fix(task-11): hatch the cut face, not its chord, and take the scaffolding with it
draw_material_hatch's handles branch read only the traced loop's `points`
and dropped the parallel `bulges`, so a cut face bounded by an arc was
hatched as the chord polygon - exactly the failure README.md and the
comment at backends/ezdxf_backend.py:1172-1176 name. MEASURED headless on
a 40x10 box closed by a 180 degree r=20 arc: boundary_from_entities ->
area 1028.318531, draw_material_hatch -> {'ok': True, 'points': 4} and
entity_measure(hatch) -> {'area': 400.0, 'exact': True}. 628.3 mm2, 61% of
the face, silently unhatched, and the payload stated no accuracy.
entity_create_hatch takes a vertex list on both engines, so an arc edge has
to reach it as vertices; the bug was dropping the curve, not the fact of
vertices. Each bulged segment is now expanded onto its real arc by
_flatten_bulge, spaced so no chord departs from it by more than the
declared HATCH_FLATTEN_SAGITTA (0.01). Same repro after: points 53, area
1027.905195 against the exact 1028.318531 - an error of 0.413 (0.040%),
and the payload says so rather than claiming exactness: `accuracy`
"flatten_tolerance" or "exact", `flatten_tolerance`, `curved_edges`,
`area` (the polygon actually written) and `boundary_area` (the loop's own
exact area) so the two can be compared instead of trusted. `accuracy` is
decided by comparing those two numbers, so a backend that reports no
`bulges` at all is still reported approximate rather than assumed exact. A
straight-sided face reads `exact` / 400.0 as before.
The handles branch also had no area guard - the "at least three points"
refusal only ever covered `boundary` - so a LINE plus a 180 degree ARC
traced to a two-vertex loop and wrote a HATCH of area 0.0 with ok: True.
That case now hatches the real semicircle (37 points, 156.880337 of
157.079633), and a loop that genuinely encloses nothing (three collinear
segments, boundary_from_entities area 0.0) is refused by name before
anything is written: "the hatch boundary encloses no area (measured 0)".
Second: boundary_from_entities does not merely compute a loop, it *writes*
one. The traced LWPOLYLINE was left in the drawing on layer 0 and named
nowhere in the result, so the caller could neither find nor delete it, and
drawing_critique / drawing_finalize scored it against the drawing under the
layer-discipline rule. MEASURED headless on a 40x10 rectangle of four
LINEs: 4 entities before, 6 after, by_type {'LINE': 4, 'LWPOLYLINE': 1,
'HATCH': 1}, the polyline on layer '0'. After: 5 entities, {'LINE': 4,
'HATCH': 1}, and the result carries traced {'handle': '34', 'removed':
True} - the boolean is reported rather than assumed, so a delete that
failed is visible. The delete runs in a `finally:`, so the refusal paths
above do not leave scaffolding either (3 entities before and after).
Third: the module SOURCE block asserted the cutting-plane line's thin
middle was "the `center` role (CENTER, 0.25 mm)" and that the pair gave
"the ISO appearance" at 2:1. engineering/layers.py:19 defines CENTER at
0.18. MEASURED headless after draw_section_line on a fresh EzdxfBackend:
layer_list reports GEOMETRY lineweight 50.0 and CENTER 18.0, i.e. 0.50/0.18
= 2.78:1. A fabricated number in a standards SOURCE block is the one thing
these blocks exist to prevent, so the block now states the measured pair,
names the ratio as 2.78:1, and does *not* quote the standard's own
wide:narrow ratio, which this module cannot transcribe. The wrong figure in

fix(task-9): put the fastener plan in projection with its elevation, and refuse a thread size that is not d
Two wrong-drawing bugs in SECTION 22.
1. _hex_points defaulted to start_deg=0, putting vertices at 3 and 9 o'clock,
so the plan of an M12 hex head measured 18 mm (across flats) across the
vertical while the elevation drew that same head 20.78 mm tall (across
corners e, silhouette edges at +/- e/4 - the projection of a hexagon with
vertices top and bottom). Place the two blocks in projection and the two
views of one part disagree. The default is now 30 deg, named HEX_START_DEG
and documented on both the constant and _hex_points as the convention the
elevation is the projection of, so a future fourth caller cannot pick the
other one by accident. The three top builders (_hex_fastener_top,
_hex_nut_top, _socket_head_top) inherit it.
2. _thread_feature read the pitch from params['size'] via the ISO 261 table
while drawing the geometry from params['d'], never cross-checking the two.
feature_spec('thread', {'d': 8.0, 'length': 20.0, 'size': 'M20'}) drew an M8
minor diameter and returned dims['pitch'] = 2.5 with ISO 261 cited as the
source - one thread's pitch on another thread's geometry, a silent wrong
number carrying a standards citation. A mismatch is now refused by name,
like every other check in the module. std_feature_draw's params description
says so.
Guard tests: the old top-view test asserted only len(points) == 6 and never a
vertex coordinate, so the orientation was untested. Added the vertex
coordinates, the plan-vs-elevation silhouette-height invariant across ISO 4014
/ 4017 / 4032, the socket screw's dk invariant, and the refused thread pair.
No ActiveX member is added or changed by either fix; both are pure geometry and
validation, so no live measurement is cited. The live AutoCAD could not be
probed for a confirmation run - GetActiveObject blocked past 150 s under
sibling contention.

feat(task-4): the orthographic view engine - silhouette, hidden lines, layout
engineering/mech/views.py projects a part model onto a view plane and returns primitive descriptions, so a test asserts geometry rather than a screenshot. The one calculation everything comes out of for a revolved part is the radial profile: the part cut into bands of constant bore and constant (or linearly tapering) outside, with every feature's radial_edit applied. The front view is that profile walked as a path and mirrored about the axis; the section cut face of the next task is the same profile walked as a closed loop, which is what stops the outline and the hatched area ever disagreeing. Chamfers and fillets do not draw over the silhouette - they substitute their corner in it, so the overshoot the critique focus looks for cannot be produced by construction, and a corner edit that finds no corner is reported rather than dropped. A band's radii are read off the segment the band's MIDPOINT lies in and the taper is evaluated at the band's own two ends. Sampling a hair inside the band to dodge the segment-boundary ambiguity - the way the plan's draft did - writes the taper slope times that inset into every coordinate the silhouette is built from: a 30 -> 10 mm cone over 20 mm then reports 14.99999 for a radius that is exactly 15, and nothing downstream can tell that it is wrong. The end view applies a real hidden-line rule: walking the bands from the viewing end, a diameter larger than everything nearer than it is drawn hidden, a bore behind material is hidden, and the near end's own circles are visible. Looking from the left reverses it. A revolved part's top view is refused, because it repeats the front. Prismatic parts get the outline in true shape with corner fillets and chamfers substituted in, and side/top thickness rectangles - the case where a hand-drawing model reliably forgets the hidden line per through feature, which here comes out of the feature itself. The honesty rule of spec section 6 is enforced in one place: a feature that emits no primitives and edits neither the radial profile nor a corner is listed in the view's omitted tuple with its own reason. Nothing is silently dropped. layout_origin places views in first-angle positions by default (the view from the right goes to the left, the view from above goes below) and flips both for third angle. It takes one additive keyword beyond the pinned signature, child, because placing a view to the left depends on that view's own width; without it the child is assumed the parent's size and every pinned call still works.

fix(task-3): keyway end-view arc, the machined face, and the chamfer's segment bound
Three defects in the feature catalogue, all faithfully transcribed from the plan text and all wrong in shipped code. 1. Keyway.prims(view="side") emitted the arc the keyway REMOVES. `Arc` is CCW start -> end, and the emitted (right wall -> left wall) is the ~31 degree cap over the slot opening, not the ~329 degrees of shaft that survives it. Measured live on AutoCAD 2026 (Documents.Add scratch doc, closed in a finally): ModelSpace.AddArc(center, radius, start_rad, end_rad) -- angles in RADIANS, CCW start -> end -- gives ArcLength 8.098 mm for the emitted 74.534 -> 105.466 deg and 86.150 mm for the reversed 105.466 -> 74.534 deg, against a 94.248 mm full circle at r = 15; StartPoint/EndPoint of the emitted arc are exactly the notch walls at x = +/-4. Swapped, so the arc now runs left wall -> right wall the long way round, and the side view's bbox goes from (-4, 11, 4, 15) to (-15, -15, 15, 14.457). 2. Hole and Pocket cut the plate from OPPOSITE faces in the same view frame: Hole ran z = 0 -> depth, Pocket z = thickness -> thickness - depth, and neither takes a face parameter. A plate carrying both showed the pocket milled from one side and the blind hole drilled from the other, silently -- omission() returns None for both, so nothing reported it. The frame comment now names the machined face (v = thickness, the face the front view looks at), and Hole drills from it: the blind floor, the counterbore step and the through bore all hang down from there, as Pocket already did. 3. Chamfer.validate bounded the axial leg against the whole part, never against the segment the chamfer sits on. A shallow lead-in passed validation and was drawn straight through a shoulder at a radius that segment does not have (size 30 at 10 deg on a 15 mm end segment: radial 5.29 < 10 so the radial guard was happy, yet `before` landed at x = 45, two segments away). New helper _anchor_segment names the segment a corner actually cuts into -- at a step, the adjacent one carrying the larger radius -- and the leg is bounded by its length, refused by name with the step it would have crossed. Tests: the keyway test asserted only primitive counts and two x coordinates, so it passed with the arc reversed; it now pins the sweep, the endpoints and the bbox. The hole test exercised only a through hole, which is symmetric; added a blind-hole-and-pocket test that pins both to the same face, and a counterbore test. Added three chamfer tests (two refusals, one that must still be accepted). Each fix was mutation-checked: reverting it fails its test.

feat(task-9): SECTION 22 - std_part_list, std_part_insert, std_feature_draw
engineering/mech/stdparts.py turns the Task 8 tables into real blocks. catalogue() searches 83 transcribed parts by designation, standard, size or family; block_spec() emits the typed primitives and DESIG/STD/SIZE/MAT ATTDEFs block_define takes, in side/top for fasteners and ISO 8826-1 simplified / ISO 8826-2 detailed for bearings; insert_std_part() defines the block once, inserts it and writes the std_part ACADMCP_MECH payload the skeleton pins, so the parts list is a read of the drawing rather than a naming convention. Threads follow ISO 6410 - minor at 0.8 x major, a thread-length limit line to the major, a three-quarter minor arc in the end view. std_feature_draw() adds a thread, a DIN 509 undercut, a DIN 471/472 groove, a DIN 332 centre hole or an ISO 3601-2 O-ring groove to geometry that already exists. Its dimensions come from the shared standards registry, never from this module: an absent table, a size outside coverage or a row missing a dimension is refused by name, and the DIN 509 relief is drawn from the profile its table publishes rather than reconstructed here. DIN 332 form R is refused outright. An unknown designation is refused with the nearest catalogue entries; nothing is drawn approximately. SECTION 22 registers the three tools in the new mech pack, with alias records (INSERT plus shop-floor synonyms in English and Turkish), a regenerated tool inventory, the README release snapshot at 207 tools in 24 groups, and the frozen group-size snapshot gaining mech: 3. Two plan corrections, both verified by running the code: * the plan's @cad_tool summaries for std_part_insert (118 chars) and std_feature_draw (130) overran discovery.serialize.MAX_SUMMARY_CHARS = 110, so tests/test_tool_registry.py::test_no_authored_summary_is_long_enough_to_be_truncated failed - they would have shipped rendered as "...". Both are shortened to 99 and 104 characters with the same content. * the plan's file list omitted tests/test_tool_packs.py, which pins the pack registry, the tool_packs report and the group count. It now carries MECH_TOOLS and distinguishes ALL_PACKS (declaration order, what "available" reports) from ALL_PACKS_ENABLED (sorted, what "enabled" reports) - those two lists stopped being the same list when "mech" was appended after "settings". No new ActiveX member is called: the module drives block_list / block_define / block_insert / entity_set_xdata / entity_create_* only. The COM path was still executed live once on AutoCAD 2026 in a scratch document created and closed by the probe: the bolt block defined with layers CENTER+GEOMETRY, attributes read back as DESIG/STD/SIZE/MAT = ISO 4014 - M12x60 / ISO 4014 / M12x60 / 8.8, the ACADMCP_MECH std_part payload round-tripped through entity_get_xdata, STD_ISO_15_6205_SIMPLIFIED inserted, and the M20 thread's three primitives landing on GEOMETRY.

feat(mech): SECTION 23 completes with centre_marks, section_line, hatch_material
centre_marks draws ISO 128-23 centre marks or full centre lines and reads
each circle's real centre and radius back out of the drawing through
entity_get instead of being told them - a radius restated from memory is
the silent wrong number this repository keeps refusing to ship. A handle
that is not a CIRCLE or ARC, and a circle in a plane tilted out of WCS XY
(which has no radius in this frame), are both refused by handle before
anything is written. The dash proportions are not transcribed here: the
prims are plain lines on CENTER, whose linetype already carries them.
section_line draws the ISO 128-40 cutting-plane line - wide segments at
the ends on GEOMETRY, the thin long-dash-dot middle on CENTER, an arrow at
each end whose head sits on the line end and points the way the section is
viewed, the same letter beyond both arrows - and returns the five-key
plane dict {p1, p2, label, direction, style} that mech_view_add(kind=
"section") consumes, so the label on the plan and the label on the view
are the same string by construction. A viewing direction parallel to the
plane is refused rather than drawn.
hatch_material hatches through standards.materials.hatch_for, so the
ISO 128-50 map and its refusal stay in one place; scale multiplies the
material's own pattern scale and angle replaces its angle. An unknown
material is refused with the list before any entity is written.
DEVIATION - one defect in the plan's own draw_material_hatch, fixed here
with two tests that fail against the plan's code. It called
entity_create_hatch with ROLE_LAYER["hatch"] without creating that layer,
the same omission review found in Task 10's draw_annotation_prims.
MEASURED live on AutoCAD 2026 (probe: GetActiveObject, Documents.Add(),
doc.Close(False) in a finally): on a scratch document whose layer table is
['0'], msp.AddHatch(0, "ANSI31", False) + AppendOuterLoop + Evaluate()
leaves the AcDbHatch in model space, and the very next statement
hatch.Layer = "HATCH" - which is the one line _apply_entity_attrs runs -
raises com_error (-2147352567, ..., 'Key not found', ..., -2145386476);
model space then still reports [('AcDbHatch', '0')] and the layer table is
still ['0'], so the refusal leaves an orphan hatch on layer 0. After
doc.Layers.Add("HATCH") the same assignment succeeds. drawing_open runs no
bootstrap, which is exactly when a cut face has no HATCH layer to land on.
draw_material_hatch now calls ensure_annotation_layers before creating the
hatch and reports layer / layers_created, as draw_annotation_prims does.
The whole task re-measured live afterwards through ComBackend on a fresh
scratch document (layer table ['0']): hatch_material -> {'ok': True,
'handle': '82', 'pattern': 'ANSI31', 'layer': 'HATCH', 'layers_created':
['HATCH']} with the entity read back as HATCH on HATCH; centre_marks on a
live CIRCLE r=12.5 -> sources [{'handle': '84', 'center': [80.0, 0.0],
'radius': 12.5}]; section_line -> 9 entities and the five-key plane; layer
table after ['0', 'CENTER', 'GEOMETRY', 'HATCH', 'TEXT']; document closed.
tests/test_mech_marks.py: 17 passed. Gates: ruff check clean, inventory
regenerated to 209 tools, test_tool_registry (engineering 12 -> 15, total
206 -> 209), test_discovery_aliases, test_tool_inventory,
test_capability_contract and test_release_consistency all pass. Full
suite: 3343 passed, the 6 pre-existing failures verified identical with
this change stashed, and
test_release_consistency.py::test_document_numbers_match_the_tree
deselected as Global Constraints instructs.

fix(task-10): ensure annotation layers live, and put the weld symbols and their dimensions where ISO 2553 puts them
Three blocking review findings in engineering/mech/annotate.py.
1. draw_annotation_prims assigned ROLE_LAYER[role] without creating the
layer. EzdxfBackend._apply_attrs adds a missing layer; ActiveX does not.
MEASURED live on AutoCAD 2026 (probe: GetActiveObject, Documents.Add(),
doc.Close(False) in finally): on a scratch document whose layer table is
['0'], draw_surface_texture(ComBackend(), at=(0,0), ra=3.2,
machining='required', lay='perpendicular', allowance=0.5) raised
"AutoCAD COM error (-0x7ffdfff7)" and left one orphan AcDbLine on layer 0
— a partial write with no rollback, on exactly the foreign-drawing path
the spec names (drawing_open runs no bootstrap). The same probe after the
fix: {'ok': True, count 6, 'layers_created': ['DIM','TEXT']}, model space
['AcDbLine' x4 on DIM, 'AcDbText' x2 on TEXT], layer table ['0','DIM',
'TEXT']. New helper ensure_annotation_layers() creates every target layer
up front, before the first entity, with its ENGINEERING_LAYERS colour /
linetype / lineweight; the result reports layers_created.
2. side='both' drew the two elementary symbols 0.4h apart — the other-side
one still stood on the (correctly omitted) identification line, so a
double-V butt weld came out as two detached halves that were not even
symmetric about the reference line. ISO 2553 places them back-to-back on
the continuous reference line: the other-side baseline is now 0.0 when
there is no identification line. tests/test_mech_annotate.py asserted the
wrong apex (-0.4*h), so the gate certified the defect; that test is
rewritten to assert the mirror pair, plus a double-fillet case.
3. For side='other' the size and length were written above the reference
line while the symbol hung below the identification line — 'a6' sat where
an arrow-side throat dimension sits, on a joint with no arrow-side weld.
Both texts now sit beside their own symbol (0.25h clear of the line it
stands on, on the symbol's side). New test covers side='other' with size
and length, and pins arrow/both unchanged.
All five new or rewritten tests fail against the pre-fix module (the layer
one with the measured 'Key not found' refusal, via a fake that models only
that measured behaviour) and pass after. tests/test_mech_annotate.py: 29
passed. Full suite: 3326 passed, 6 pre-existing failures unrelated to this
change (verified identical on the branch tip with the change stashed),
test_release_consistency.py::test_document_numbers_match_the_tree
deselected as instructed. No tool registration changed, so
docs/tool-inventory.json regenerates byte-identical.

feat(task-3): the feature catalogue and its standards tables
engineering/mech/features.py is the nineteen typed features of spec section 5,
each answering the same four questions - is my placement legal, what do I
contribute to this view, to a cut face, and what dimension do I want - plus the
five structural hooks the view engine needs: removal_box, radial_edit,
corner_edit, outline_edit and omission. Pure arithmetic; a test asserts emitted
primitive tuples, not a screenshot.
Nothing restates a table the repository already owns: Keyway takes its width
and depth from engineering.keyway (DIN 6885-1) and is refused by name outside
that table's bore range; GearTeeth takes its outline from engineering.gear's
involute generator and is refused when its tip diameter disagrees with the
segment it sits on.
standards/threads.py transcribes ISO 261 Table 1 and Table 2 - first-choice
M1.6-M64 plus second-choice M14/M18/M22/M27/M33/M39/M45/M52/M60 - and computes
ISO 724's basic minor and pitch diameters from ISO 68-1's own formula, pinned
against the published values (M20x2.5 -> 17.294 / 18.376). The remaining
second-choice diameters, every third-choice diameter and fine pitches below M8
are not transcribed and are refused by name, never interpolated. The drawing
rules are ISO 6410: minor at 0.8 x major, a thread-length limit line across the
major, a three-quarter circle in the end view, and an internal thread whose
section hatch runs to the major diameter.
standards/{undercuts,rings,centres,orings}.py ship DIN 509, DIN 471/472,
DIN 332-1 and ISO 3601-2 with their SOURCE, their row-key contract and an
**empty** row set. That is deliberate and is the track's table rule taken at its
word: a row that could not be verified against the standard is not shipped,
because a wrong relief depth or groove diameter is a wrong workshop drawing
while a narrow table is merely narrow. Every lookup is refused by name and says
what to transcribe and where; the features accept explicit dimensions so the
geometry is fully exercised, and DIN 332 form R is refused outright rather than
approximated by the straight 60 degree cone of forms A and B. Filling any of
these tables later is a data edit with no code change, and a shape test already
fails any row that lands without a column the drawing code reads.
Three deviations from the plan text, each measured rather than assumed
(the merge agent should keep exactly one copy of the first):
1. standards/__init__.py (Task 1, on main) refused a registration with no rows
("registered no rows"), which would have made the four not-transcribed
tables impossible to register at all - and registering them is what keeps a
later transcription a data edit. register() now refuses a rows argument that
is not a dict and accepts an empty one; two tests in tests/test_mech_standards.py
pin both halves. No existing test asserted the old refusal.
2. ORingGroove's housing kind is carried by `housing`, not `kind`. A dataclass
field named `kind` overwrites the discriminator _Base.to_dict() writes:
measured, Probe(id='og').to_dict() == {'kind': 'radial', 'id': 'og'}, so
feature_from_dict would then refuse its own payload as an unknown feature
kind and no part carrying an O-ring groove could round-trip through XDATA.
A new test pins the round trip.
3. The plan's end-chamfer test asserted after == (75.0, 10.0) - the corner
itself - and before == (72.0, 8.268), a point on neither surface. The real
edit is before (72.0, 10.0) on the cylinder and after (75.0, 8.268) on the
end face, consistent with the 45-degree start chamfer the same file pins.
The test was corrected to the measured geometry; the behaviour is unchanged.

feat(mech): SECTION 23 opens with surface_texture and weld_symbol
ISO 1302:2002's seven transcribed symbol-proportion rows (text height -> line width d', short-leg height H1, minimum height H2) drive the 60 deg vee, the machining-required bar at H1, the machining-prohibited circle inscribed in the vee, and the all-around circle at the kink; the Ra/Rz values, the process, the lay symbol and the machining allowance land around the extension line, which grows with the widest of them. A text height outside the seven rows is refused by name rather than interpolated, and ISO 1302 is accepted as an alias designation for drawings still issued under it - the graphical symbol is the same one. ISO 2553:2019's reference line, dashed identification line (omitted for a symmetrical weld, as the standard permits), size written before the symbol, length and pitch written after it, field-weld flag, all-around circle and process tail. Six elementary symbols are transcribed - square, single-V, single-bevel, single-U, single-J, fillet. The rest of the elementary table is deliberately not shipped: a weld kind outside the six is refused with the list of the six, because a guessed weld symbol is a wrong instruction to a welder. Both tools place the symbol on a plain leader - a line plus an arrowhead with the proportions the backend's own mleader already draws - rather than through leader_create_mleader, which refuses empty text and would hang an MTEXT label off every symbol. Proportions neither standard dimensions (the all-around circles, the flag, the identification line's dashes, the text pitch and the character width estimate) are named constants documented as this implementation's declared choices, never as transcribed values. No new ActiveX member is called: both tools compose LINE / ARC / CIRCLE / LWPOLYLINE / TEXT through the entity-creation contracts both engines already implement, so no live COM probe was needed.

feat(task-8): ISO fastener and ISO 15 bearing tables, transcribed and pinned
engineering/mech/standards/fasteners.py carries ISO 4014:2011 / ISO 4017:2014 head dimensions (s, k), ISO 4032:2012 nut heights, ISO 7089:2000 washer d1/d2/h and ISO 4762:2004 socket head cap screws, plus the ISO 261:1998 coarse pitch column. bearings.py carries the ISO 15:2017 deep groove boundary dimensions for 6000-6010, 6200-6210 and 6300-6310. Only the ISO 261 first-choice sizes ship. M14/M18/M22/M27/M33, everything above M36 (above M24 for ISO 4762), the 618x/619x/16xx bearing series, bore numbers above 10 and every suffixed bearing variant are refused by name rather than interpolated: a narrow table is merely narrow, a wrong row ships a wrong workshop drawing. Across-corners e is derived geometry (2s/sqrt(3)), so no e column had to be transcribed at all, and the ISO 8826-1 cross and ISO 8826-2 element-symbol fractions are declared drawing conventions, not table values. No ActiveX member is called by this task, so no live AutoCAD probe was needed; the two modules are pure tables and pure arithmetic.

feat(task-2): the mechanical part model - RevolvedPart, PrismaticPart, build_part
engineering/mech/part.py is the model the whole track draws from: a revolved stack of segments along +X, or a closed prismatic outline plus a thickness, each carrying a list of typed features. Pure arithmetic - no backend, no async, no DXF - which is what lets the view engine be tested without a drawing. Every refusal fires before anything is drawn and names the offending path the way pid_from_spec does: a non-finite or non-positive number as segments[2].d_outer, a bore that is not smaller than its outside (a bore that changes diameter is two segments), an outline with fewer than three distinct vertices, an outline that crosses itself (engineering.measure.is_self_intersecting - the shoelace cancels crossed lobes rather than failing, so a bowtie would otherwise measure 0.0), an unknown material, an unknown segment key, a duplicate feature id. Two gates are the reason this is a model rather than a dict: a feature whose placement is off the part is refused by its own name and by the range it missed, and two features that would remove the same material are refused with both names and the overlapping box. Neither is clamped. part_to_dict round-trips through build_part, which is what lets mech_part_draw write the model onto the drawing as ACADMCP_MECH XDATA and mech_view_add read it back months later without the caller re-describing the part. Two fixes to the plan's own code and test list, both recorded in deviations: _features_from imported engineering.mech.features unconditionally, so a featureless part - every fixture in this module, and both round-trips - died on ModuleNotFoundError until Task 3 lands; the import now happens only when there is a feature dict to build. And the plan's test file omitted test_a_duplicate_feature_id_is_refused while its own gate deselects it by name, so the duplicate-id refusal the commit message claims went unpinned; the test is written here and Task 3 turns it green.

feat(mech): shared foundation - primitives, XDATA codec, standards registry, ISO 128-50 materials
engineering/mech/ opens with the four modules every track-B/G branch imports, so the four worktrees can be cut from this commit and none of them has to invent a name the others will conflict with. - primitives.py: the typed descriptions the pure modules emit (Line, Arc, Circle, Poly, HatchArea, Text, DimIntent) with bbox / translate / rotate / scale, and ROLE_LAYER - the one place an ISO 128 line role becomes a layer name, so no module hardcodes a layer. The arc bbox sweeps its quadrants: a 0-180 arc reports y=+r, not its endpoints, which is what keeps the view layout from stacking two views on top of each other. - xdata.py: the ACADMCP_MECH codec in Track A's shape - a 1001 application marker, 1000 chunks of at most 255 ASCII characters, the 16 KB per-entity ceiling enforced before anything is written, and a foreign application, a corrupt chunk stream, a wrong version or an unknown kind refused with ValueError instead of decoded into something plausible. - standards/__init__.py: the table registry. A size outside the coverage is refused against the coverage; a size inside it that is not a listed row is refused against the rows. Nothing is interpolated, an ambiguous variant is never resolved by taking the first row, and a registration whose SOURCE does not name the table it was transcribed from is refused. - standards/materials.py: the section-hatch map for nine materials. ISO 128-50 standardises only the general hatching (narrow continuous lines at 45 degrees) - that is acadiso.pat ANSI31 and what engineering/gear.py already draws for steel. The distinguishing symbols are ASME Y14.2M's section lining as shipped in AutoCAD 2026's acadiso.pat, read off the installed file; cast iron's departure from ASME and the absence of any mechanical symbol for concrete and wood are stated in the rows themselves. Angles are 0.0 because the patterns already carry 45 degrees, and the two architectural patterns' scales are derived from the ANSI31 line spacing and recomputed by the test rather than chosen. No tool is registered here. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FKFStjEFzpGyLq5bMpWxTd |
